IMPROVEMENT IN STEAM-BOILER ATTACHMENTS.

Specification forming part of Letters Patent No. 292,265, dated J one 19, 1877; application filed May 2, 1877.

To all whom it may concern Be it known that I, SIMON KEMPER, of Hermann, Gasoonade county, and State of Missouri, have invented an Improvement in Steam-Boiler Attachment, of which the following is a specification The object of this invention is to provide steam-boilers with a means to enable the operator to see inside the boiler, and thus notice the height of the water-level, also the action of the water. This to accomplish, my invention consists in providing the boiler with a transparent medium, such as glass, and to the peculiar manner of joining the same steamtight to the boiler, and as will hereinafter appear.

Of the drawing, Figure 1 is a front elevation. Fig. 2 is a longitudinal section. Fig. 3 is a rear elevation.

A represents the boiler. I provide the boiler with a hand-hole to contain the parts, as follows: B is the frame or casting that contains the glass or mica, or transparent media 6. The rear part of the frame B is recessed, to form a seat at N, for the glass. (See Fig. 2.) Between the glass 1) and seat b intervenes a packing, I), (see Fig. 2,) to obtain a steamtight joint. The glass fills up the chamber in the frame B, and presents a face flush with the rear face of its frame and in order that the glass can be further secured by the ring 0. The ring 0 has its opening somewhat smaller than the face of the glass, in order to present a supporting-edge at c, which is to fasten the glass. (See Figs. 2 and 3.) The glass is thus held by the bearings at b and c.

The ring is placed contiguous to the rear face of the glass, and by screw-bolts at c said ring is securely fastened to the frame B. (See Figs. 2, 3.)

The frame B has its front face cast with a projecting hearing at d, (see Figs. 1, 2,) so as to tit flush in the opening of the boiler-plate, the joint at d being made steam-tight by the packing d (See Fig. 2.) The frame B with all its described parts is, lastly, united to the boiler by means of screws d and arches d secured by nuts d (See Figs. 1 and 2.)

In this wise the transparent media can be most practically (with the necessary steamtightjoint) made to form part of the boiler. The operator can see through the window and keep posted as to the condition of the waterlevel and the action of the water, 8w.

Water-gages frequently indicate too much water when the engine is running, and as soon as the engine is stopped the water is too low.

My invention is reliable, and affords a means of safety in the use of boilers.

What I claim is The combination of the frame B, transparent media b, packing b al ring 0, arches d and fastening-bolts, all said parts being constructed and arranged as and for the purpose set forth.

In testimony whereof I have hereunto set my hand.
